me ai om tt concern:

,de own that l, FRANK C. ANDERSON, a citi/ien o i'vthe UnitedStates,residing at Cincinnati, in the county of Hamilton and State'otizlhio, have invented certain new useful improvements inSwitch-Stands, et which the following is a specification.

My invention re' es to improvements in switch stands of At8() degreethrow or si 'teton type, and more particularly to the position andarrangement of the crank and A pin ot the operating shaft relatively tothe track, tc the ulcrum head of the. operating shaft and to themovement of the crank pin Hlively to the track as shown'in my coidapplication, Serial No. 594,465.

The object of my invention is to construct and arrange a switch stand ofthe ordinary itil); degree throw type in such a manner the switch standcan be installed and operated independently ont switch interlockingmechanism and operate to throwthe si ch points and targetin the usualman-A ner, and which is adapted to engage and opmay he installed eithersimultaneously with or subsequently to the installation of said itchstand, and connected to said switch and operated thereby in such a manasto operate thel switch interlocking lvisita, switch Apoints and targetat a operation ot the opera-ting lever. .ier object ot my invention isto so and arrange the crank and crank the cperating 'shaft of the switchd ci? 'the ordinary 180 degree throwton type that theswitch interlockingiiiiiechanism, switch points and target will he operated when theswitch-is being irown to open or closed position, hy i le throw of the.operating lever.

etoliore switch stands of the usual i90 ree throw type have beenKconstructed arranged with the crank set at right es to the track whenthe switch is in fr open or closed position, and when so and, it hasbeen impossible to operate )cking mechanism in connection with switchstand by a single operation of the operating lever without an entirelydierenttype out switchnstand, consisting of one or more levers andvarious combinations ot" mechanism. lt has also been impossible tooperate-interlocking mechanism in connection irijtha switch standconstructed inthe crate switch interlocking mechanism whichA theinterlocking mechanism independently of the operation of the switchstand, thus requiring two operations by the operator in opening ntheswitch. Thus when'switch stands of the ISO'degree throw type wereinstalled, .it was impossible to install there- 'with interlockingmechanism which could be operated in connection with said stand by asingle operation'of the throwing lever but an additional lever or foottreadle, and an additional operation to operate the inter'lockingmechanism' would be required.'

lt will, therefore, be seen that I provide means whereby the ordinaryswitch stand.

of this type may be utilized and installed and operate the switch in theusual manner,

either separat-ely'or'in .connection with in terlock'ing mechanism, asdesired, thus permittin'g the installation of the switch stands andinterlocking .mechanism at different times if desired and still beenabled to opcrate the interlocking mechanism and switch stand by oneAoperation of the throwing lever.

My invention consists 'in providingv a switch stand of the ordinary 180'degree throw' skeleton't-ype, having an operating shaft with a crankthereon, with, a crank pin on said crank set'in such a manner relativeating shaft at right angles to the track that said crank pin willl moveacross .said line in f an arc ota circle or in a direction substantially parallel with the track suliiciently to operate interlockingmechanism before the movement of 'said crank pin throws .the switchpoints ,to open position My invention also consists in the peculiarconstruct-ion', combination and arrangement or" parts as herein setforth and claimed.

ln the accompanying 'drawings which serve to illustrate theconstruction, arrangement, application and use of my invention: Figure l'is a plan View of a switch stand equipped with my invent-ion andinstalled separately and independently fromv switch interlockingmechanism. Fig. 2is,a diagrammatic view illustrating the peculiarpositioning or arrangement of the crank and crank pin` of theoperatingshaftgwith relat-ion to the switch stand. Fig. 3 is aside elevationpartly in section showing a preferred switch points. Fig. 4 is adiagrammatic view showing means for connecting the opery ating shaftwith interlocking mechanism.

Fig. 5 is a plan view similar to Fig. 1, but

showing interlocking mechanism adapted t0 be operated by my invention,in connection with the switch standby one operation of the operatinglever. Fig. v6 is a front elevation of the switch stand of the ordinary180 degree throw skeleton type, the crank pin being shown set off of aline drawn centrally through the operating shaft at right angles to thetrack. .Fig 7 is a diagrammatic view showing the different positions ofthe which are fastened upon ties 3, and upon which the point rails 6 areadapted to'slide ,into and out ofengagement with the stock ra1ls.4 inopening and closing the switch.`

The feet 2 of the switch stand are provided with lugs 7, which areadapted to coincide with slotsin the attachments which may be used inconnection with the switch stand,

such for instance, as interlocking meehahism.

shown in Fig. 5. The switch stand 1 has a top plate 8, provided withslots 49 and 9 and is of the usual construction of switch stands ofthe180 degree type. It is provided with a cross brace l() to which isfastened a strap 11 adapted lto form a lower bearing for the operatingshaft 12 of the switch stand. Another strap 13 is fastened atthe top ofthe Switch stand, and forms an upper bearing for the main operatingshaft 12.

To form a suitable lower support for the target shaft 14. T, provide across supporting arm 15. formed integral with the switch stand, andprovided with an enlarged central portion 16 to receive the target shaft14.

The main operating shaft 12 is provided with the usual fulcruin head 17on the top of the switch stand top plate 8. to which is pivoted theoperating lever 25 in the usual manner. The fulcrum head 17 'is adapted"to abut against the stops 18 and 18 provided on opposite sides of thetop plate S.

' The target shaft 14 is adapted to be thrown 90 degrees when theoperating shaft is beingthrown 180 degrees. This is accomplished in theusual way, by means of a target shaft operating arm 19, securely fas--tened to the target shaft. and extending over the fulcrum head 17. Thefulcrum head is Aprovided with a stud 20 on the top thereof adapted toengage a slot 21 in the target shaft operating arm 19.

My invention which add to a switch stand will now be described. Thebottom lend of the operating sha-ft 12 is provided with a crank 22,which may be either formed integral with the 'operating shaft 12 orotherwise fastened securely thereon. The

crank pin 26 on said crank when in its nor-l mal posit-ion, (that iswhen the switch is closed) will set five or more degrees ofi' of a linedrawn centrally through'l the operating shaft at right angles tothe'tiack, and is adapted to move across said line when the switch isthrown to open position. Suitable holes 23 shown in Figf, are preferablyprovided in the operating shaft 12 just above Athe support 10, for theoperating shaft of lnormal position of the crank 22 is' shown in solidlines. The distance from its normal position to its first dotted lineposit-ion shown is equal to 40 degrees, and the distance from its solidline positionvto its farthermost dotted line position is 180 degrees,thus coinciding with the distance that the fulcrum head 17 is adapted tomove, the fulcrum head also being rigidly secured upon the operatingshaft 12. In Fig. 2 an are 31 is shown drawn from the center line ofsaid pin 26 to the same center shown in its first dotted line position,and a straight line, is drawn between the centers forming a chord 28across the arc. This is done to'illustrate the slight distance that thepointrail would to the rstdotted line position, and as a y rule, theconnections of t-he operating rod and the connections between theoperating rod and the point rails will imperceptibly vield that amountwithout injuriously affect.- ing or springing the connect-ions. Itisevident that when the crank 22 has reached its rst dotted line position,that the point rails then begin to move away from the stock rail. As themovement of the crank is continued thc point rails continue to moveoutwardly until the crank has reached its extreme position, shown indotted lines. amounting to T40 degrees from its first dotted line posi-4tion. or 180 degrees from its first'position which is .shown in heavylines. The fulcrum head 17 during this movement of said crank pin hasmoved 180 degrees from slot 9 in the top plate 8 to the other slot 9diametrically opposite.

iVhile I have shown thecrank pin disposed at an angle of 20 degrees oli.of .a

is-fi line drawn centrally through said operating shaft at right anglesto the track, I do not wish to be limited to this yexact angle, but thesame can be varied to suit the convenience of the particular connectingmechanism for the attachments.

The distance of the throwof they switch points is determined by therelative distance of the center ofthe crank pin with the center of theoperating shaft, for with my invention the point rails are operated by amovement of 140 degreesof the crank pin.

In Fig. 6 I have shown the movements-of an interlocking lunger 29 withrelation to an interlocking ar 30 when operated with my invention, andfrom which it will be seen that the plunger is withdrawn from engagementwith the interlocking bar during the first 40 degree movement,` of theoperating crank pin substantially parallel with the track, andthatit.ren1a.ins disengaged from A said interlocking bar during theremaining movement of 140 degrees to open the switch, and will notrengage the interlocking bar .r unt-il the switch has been thrown toclosed position.

I claim: l. In a switch stand, a vertical operating to the track whenthe switch is in either open or closed position, said crank pin beingadapted to move across said line .when the switch is thrown from oneposition to another, a throwing or operating lever adapted to be thrownmore than 90 degrees', and means for operatively connecting .said crankto the pointrails of a. switch, for the purposes set forth.

2. In a switch stand, an operating shaft with a crank thereon, a crankpin-on said 1crank, set off of a line drawn centrally through saidoperating shaft atright angles to the track, and connected to the pointrails ofa switch, and means for operating said shaft to throw said prankpin across said line in an arc of a. circle or on a line substantiallyparallel with the track without moving the point rails to open position,substantially as and for the purposes specified.
